The authors studied strategic aspects pertaining to adoption drivers, challenges and strategic value of Additive Manufacturing Technology (AMT) in the Indian manufacturing landscape. An exploratory qualitative study with semi-structured in-depth personal interviews of experts was completed and the data was content analysed. Indian firms have identified the need for AMT in R&D and prototype generation. AMT implementation helps Indian firms in mass customization and eases the manufacturing of complex geometric shapes. This study insights would help AMT managers in emerging economies to enable adoption drivers, overcome challenges and add strategic value with AMT. This is one of the very first studies on AMT with theoretical perspectives on the Miltenberg framework, adoption drivers, challenges and strategic value in the Indian manufacturing landscape.

Additive manufacturing (AM) is one of the most trending technologies nowadays, and it has the potential to become one of the most disruptive technologies for manufacturing. Academia and industry pay attention to AM because it enables a wide range of new possibilities for design freedom, complex parts production, components, mass personalization, and process improvement. The material extrusion (ME) AM technology for metallic materials is becoming relevant and equivalent to other AM techniques, like laser powder bed fusion. Although ME cannot overpass some limitations, compared with other AM technologies, it enables smaller overall costs and initial investment, more straightforward equipment parametrization, and production flexibility.This study aims to evaluate components produced by ME, or Fused Filament Fabrication (FFF), with different materials: Inconel 625, H13 SAE, and 17-4PH. The microstructure and mechanical characteristics of manufactured parts were evaluated, confirming the process effectiveness and revealing that this is an alternative for metal-based AM.

Purpose Recent developments in additive manufacturing (AM) technology have emphasized the issue of social impacts. However, such effects are still to be determined. So, the purpose of this paper is to map the social impacts of AM technology. Design/methodology/approach The methodological approach applied in this study combines a literature review with computer-aided content analysis to search for keywords related to social impacts. The content analysis technique was used to identify and count the relevant keywords in academic documents associated with AM social impacts. Findings The study found that AM technology social impacts are still in an exploratory phase. Evidence was found that several social challenges of AM technology will have an influence on the society. The topics associated with fabrication, customization, sustainability, business models and work emerged as the most relevant terms that can act as “pointers” to social impacts. Research limitations/implications The research on this subject is strongly conditioned by the scarcity of empirical experience and, consequently, by the scarcity of data and publications on the topic. Originality/value This study gives an up-to-date contribution to the topic of AM social impacts, which is still little explored in the literature. Moreover, the methodological approach used in this work combines bibliometrics with computer-aided content analysis, which also constitutes a contribution to support future literature reviews in any field. Overall, the results can be used to improve academic research in the topic and promote discussion among the different social actors.

The degradation of natural resources as a result of consumption to support the economic growth of humans society represents one of the greatest sustainability challenges. In order to allow economic growth to continue in a sustainable way, it has to be decoupled from the consumption and destruction of natural resources. This thesis focuses on an innovative manufacturing technology called additive manufacturing (AM) and its potential to become a more efficient and cleaner manufacturing alternative. The thesis also investigates the benefits of accessing the technology through the result-oriented Product-Service Systems (PSS) approach. The outcome of the study is the quantification of raw materials and energy consumption. The scope of study is the application of AM in the scale model kit industry. The methods used are the life cycle inventory study and the system dynamics modeling. The result shows that AM has higher efficiency in terms of raw material usage, however it also has higher energy consumption in comparison to the more traditional manufacturing techniques. The result-oriented PSS approach is shown to be able to reduce the amount of manufacturing equipment needed, thus reducing the energy and raw materials used to produce the equipment, but does not completely decouple economic growth from the consumption of natural resources.

Additive manufacturing (AM), sometimes called 3D-printing is a group of manufacturing technologies that build up a product using a layer by layer technique and provides new ways of manufacturing parts and products. The Company in this thesis wants to make AM a tool in their manufacturing toolbox. When introducing this manufacturing method, new processes and methods have to be developed. The purpose of this thesis is to develop a methodology that will help the designers when identifying parts that should be manufactured using AM. The development of this methodology has followed the principles of service design which is a holistic interdisciplinary approach where methods from different disciplines are combined to create benefits to the end user experience. Before the development process, a large background study was performed to gather detailed information within the area of AM. The methodology concept was then developed through five iterative cycles where methods such as interviews, trigger material, questionnaire, case study and stakeholder mapping were used. The thesis resulted in an AM handbook with information regarding the technology and a five step methodology for choosing when and why to use AM as a manufacturing method. Step one is to identify the AM potential in a product which is based on complexity, customization and production volume. Step two is to specify requirements of the products, this can be surface finish, tolerances etc. The third step in the design methodology is part screening, which is the making of the final decision about if the product should be printed and if it can be printed. The fourth step is to choose an AM technology based on the requirements specified in step two by providing information about the technologies’ restrictions and possibilities. Step five in this methodology is the design of AM products and provides simple design guidelines. It has been shown that a dynamic task is best solved through working with dynamic methods, therefore service design approach is a flexible and good fit for this thesis. This design methodology is only a part of the AM-area and needs to be supplemented with other knowledge within the area. The first step after implementing this handbook is to investigate how the organization and business is affected when implementing AM.
Additiv tillverkning (AM), även kallat 3D-printing, är benämningen på en grupp tillverkningstekniker där en produkt byggs lager för lager. Denna masteruppsats har utförts i samarbete med ett svenskt industriföretag som levererar lösningar inom tillverkningsindustrin, i rapporten kallat Företaget. Genom att utveckla nya designprocesser och metoder vill Företaget inkludera AM i sin tillverkningsstrategi. Syftet med detta masterexamensarbete var att utveckla en metodik för hur urval och utveckling av produkter anpassade för AM ska ske. Utvecklingen av metodiken följer principerna för tjänstedesign, vilket innebär ett holistiskt tvärvetenskapligt arbetssätt där metoder från olika discipliner kombineras för att skapa en positiv upplevelse för slutanvändaren. Innan utvecklingsprocessens start gjordes en stor bakgrundsstudie för att införskaffa kunskaper kring AM. Därefter utvecklades en metod genom fem iterativa cykler där metoder som intervjuer, triggermaterial, frågeformulär, fallstudier och stakeholdermapping användes. Masteruppsatsen resulterade i en handbok med information kring teknikerna och en metodik i fem steg för att välja när och varför AM bör användas som tillverkningsmetod. Första steget är att identifiera AM potentialen hos en produkt, vilket baseras på komplexitet, kundanpassning och produktionsvolym. I steg två ska produktkrav specificeras, exempel på sådana krav är ytfinhet och toleranser. Tredje steget i metoden handlar om en produkt-undersökning under vilken ett slutgiltigt beslut fattas angående om produkten kan och bör tillverkas. I fjärde steget sker valet av teknik baserat på de produktkrav som specificerats i steg två, genom att information ges angående teknikens möjligheter och begränsningar. Femte steget i metoden handlar om designen av AM produkter och förser konstruktören med enklare riktlinjer för designen. Utveckling av en metodik kräver ett dynamiskt arbetssätt och principerna inom service design visade sig passa bra för detta projekt. Det visade sig också att den resulterade metodik behöver kompletteras med information i framtiden. Det behövs även fastställas tydliga mål för AM i företaget och vilket syfte implementeringen av denna nya process innebär

Additive manufacturing (AM), also called 3-dimensional printing (3DP), emerged as a disruptive technology affecting multiple organizations' business models and supply chains and endangering incumbents' financial health, or even rendering them obsolete. The world market for products created by AM has increased more than 25% year over year. Using Christensen's theory of disruptive innovation as a conceptual framework, the purpose of this multiple case study was to explore the successful strategies that 4 individual managers, 1 at each of 4 different light and high-tech manufacturing companies in the Netherlands, used to adopt AM technology into their business models. Participant firms originated from 3 provinces and included a value-added logistics service provider and 3 machine shops serving various industries, including the automotive and medical sectors. Data were collected through semistructured interviews, member checking, and analysis of company documents that provided information about the adoption of 3DP into business models. Using Yin's 5-step data analysis approach, data were compiled, disassembled, reassembled, interpreted, and concluded until 3 major themes emerged: identify business opportunities for AM technology, experiment with AM technology, and embed AM technology. Because of the design freedom the use of AM enables, in combination with its environmental efficiency, the implications for positive social change include possibilities for increasing local employment, improving the environment, and enhancing healthcare for the prosperity of local and global citizens by providing potential solutions that managers could use to deploy AM technology.

Additive manufacturing (AM) is a forthcoming technology which has received much attention during recent decades and is currently on its journey from prototype to small scale production. The final component is made layer upon layer, hence bringing wider opportunities such as design freedom, flexibility, and optimal material usage, etc. Rapid advancements in AM technology in terms of speed, dimensional accuracy, surface finish and repeatability, enable production of functional end use parts in tolerable volume. The research is conducted in cooperation with Atlas Copco Industrial Technique (ACIT) to explore the path towards using AM as a tool for low volume production. Currently, AM technology is widely used for prototyping at ACIT. Therefore, the purpose of the thesis project is to investigate and recommend a design methodology and guidelines for shifting from prototype to small scale production through AM. However, introduction of AM in small scale manufacturing requires its consideration right from the initial stage of product development. Initially, a thorough background study was done to understand the AM technology and its current advancement with respect to technology maturity and market aspects. The background study includes literature review, market study, interviews, visits to AM service providers, AM exhibitions, etc. Market research aided the study to be focused on two technologies i.e. Selective Laser Melting and Binder Jetting. Due to current limitations of AM technology, not all parts are good candidates to exploit the potential in AM. Considering this, questionnaires were prepared based on the literature study which was later used to get the potential part candidates for AM from mechanical designers at Research and Development, Nacka. The proposed part screening methodology categorizes parts by three main driving criteria and further leads to a technical and economical evaluation. Through bottom up approach for part screening, parts with highest potential in AM were identified and redesigned, facilitating AM conformal designs. Moreover, the parts were further utilised to propose design methodology and guidelines that could aid designers in designing parts for AM. The design methodolgy involves four stages including information phase, assessment phase, design phase and detail design phase. The thesis project resulted in selection and redesign of components with potential in AM while adding values through part consolidation, light weight design using topology optimisation and cost reduction, etc. The earlier the consideration of manufacturing technology in thedevelopment phase, the better the final design in terms of manufacturability. With respect to AM, this is a very crucial aspect, as complexity comes with almost no cost. Therefore, a simulation driven design process in which one starts the development with an optimised concept or concept designed for function can be manufactured thus leveraging the benefits of AM.
Additiv tillverkning (AT) är en tillgänglig teknologi som har fått mycket uppmärksamhet under de senaste decennierna och som för närvarande är på väg från prototypappliceringar till småskalig produktion. Den slutgiltiga komponenten är framställd genom att addera lager på lager och medför därmed vida möjligheter såsom designfrihet, flexibilitet och optimal materialanvändning, etc. Med anledning av snabba tekniska framsteg inom AT vad gäller hastighet, dimensionell noggrannhet, ytfinish och repeterbarhet, möjliggörs produktion av funktionella slutprodukter i tolerabla volymer. Forskningen är genomförd i samarbete med Atlas Copco Industriell Teknik (ACIT) med syfte att utforska vägen mot användning av AT som ett verktyg vid låga produktionsvolymer. I nuläget används AT flitigt för att skapa prototyper inom ACIT. Syftet med detta masterprojekt är därför att undersöka och rekommendera en designmetodik samt riktlinjer för att skifta från prototypappliceringar till småskalig produktion med AT. Emellertid kräver en introduktion av AT för småskalig produktion eftertanke redan i de inledande stadierna av produktutvecklingen. Till att börja med utfördes en grundlig bakgrundstudie för att omfatta AT som teknologi och dess nuvarande framsteg med avseende på teknologisk mognad och marknadsaspekter. Bakgrundsstudien innehåller litteraturstudie, marknadsstudie, intervjuer, besök hos tjänsteleverantörer av AT, utställningar med fokus på AT, etc. Marknadsundersökningen understödde ett fokus av studien mot två teknologier, nämligen Selektiv Lasersmältning (Selective Laser Melting) och Bindemedelstrålning (Binder Jetting). Med anledning av dagens begränsningar inom AT är inte alla typer av komponenter passande kandidater för att undersöka potentialen av teknologin. Med detta i beaktande förbereddes frågeformulär, baserade på litteraturstudien, som sedan användes för att med hjälp av mekaniska designers vid R&D i Nacka, identifiera potentiella komponenter att använda för AT. Den föreslagna metodiken för att undersöka komponenter kategoriserar komponenter genom tre drivande kriterier och leder i därefter till en teknisk och ekonomisk utvärdering. Genom en bottom-up approach för undersökande av komponenter, identifieras och omdesignas komponenter med högst potential för AT, vilket främjar en lämplig design för AT. Dessutom användes dessa komponenter för att föreslå en designmetodik samt riktlinjer som kan vara till hjälp för designers vid design av komponenter för AT. Designmetodiken innefattar följande fyra steg: informationsfas, bedömningsfas, designfas och detaljerad designfas. Masterprojektet resulterade i val och omdesign av komponenter med potential för AT samtidigt med värdeaddering genom sammanslagning av komponenter, design med lätt vikt genom optimering av topologi och kostnadsminskning, etc. Ju tidigare beaktande av produktionsmetod i utvecklingsfasen, desto bättre slutdesign med avseende på producerbarhet. Detta är en kritisk aspekt när det kommer till AT, eftersom komplexitet nästintill adderas kostnadslöst. Därför kan en simulationsdriven designprocess, i vilken utvecklingen börjar med ett optimerat koncept eller ett koncept designat för funktion, komma i produktion och maximalt utnyttja fördelarna av AT.

Additive Manufacturing is a fast-developing technology that is considered to be a game changer in the manufacturing industry. However, a technological innovation itself has no single objective value for a company. Indeed, it is widely acknowledged that the key aspect of a successful commercialization of a technological innovation is the linkage of the technology and the business model. Based on a qualitative study, which presents how companies have to develop their business model to commercialize AM, we conducted interviews with two Swedish small and medium-sized enterprises, which plan to invest in Additive Manufacturing. These two companies are HGF, a manufacturer of thermoplastic elastomers and rubber products, and Tylö, a manufacturer of heaters, steam generators, saunas, steam showers, and infrared saunas. In our analysis, we decided to analyse the cases successively, according to the nine building blocks of the Business Model Canvas. Firstly, we conducted a within-case analysis to analyse each case isolated from each other, and secondly a cross-case analysis to find possible nexuses, relations or, contrasts. The chapter conclusion provides an overall discussion of the most important findings emerging from the analysis with regard to the required changes within the current business model to capture value from the technology. We could find some disparities for two building blocks (channels and revenue streams). Thus, this implies that there is no universal approach to develop the business model to introduce Additive Manufacturing. Nevertheless, most of the required adjustments show accordance. While three building blocks turned out to remain largely the same (key partnerships, cost structure, and customer segments), four building blocks require important changes (key activities, key resources, value propositions, and customer relationships. The most important implications for those building blocks are presented in the following: Key activities: Upgrade product development Key resources: Establish additional production facilities (3D-printers, etc.) Gather new knowledge about AM Value propositions: Offer customized products Customer relationships: Closer relationship with the (end) customer Enhance customer co-creation

Additive manufacturing processes, which utilize selective deposition of material rather than traditional subtractive methods, are very promising due to their ability to build complex, highly specific geometries in short periods of time. Three-dimensional direct inkjet printing is a relatively new additive process that promises to be more efficient, scalable, and financially feasible than others. Due to its novelty, however, numerous technical challenges remain to be overcome before it can attain widespread use. This thesis identifies those challenges and finds that material limitations are the most critical at this point. In the case of deposition of high viscosity polymers, for example, it is found that droplet formation is a limiting factor. Acoustic resonance jetting, a technology recently developed at Georgia Institute of Technology, may have the potential to address this limitation because it generates droplets using a physical mechanism different from those currently in use. This process focuses ultrasonic waves using cavity resonances to form a standing wave with high pressure gradients near the orifice of the nozzle, thereby ejecting droplets periodically. This thesis reports initial exploratory testing of this technologys performance with various material and process parameters. In addition, analytical and numerical analyses of the physical phenomena are presented. Results show that, while the pressures generated by the system are significant, energy losses due to viscous friction within the nozzle may prove to be prohibitive. This thesis identifies and begins evaluation of many of the process variables, providing a strong basis for continued investigation of this technology.

Increasing application of Additive Manufacturing (AM) in industrial production demands product reimagination (assemblies, subsystems) from an AM standpoint. Simulation driven design tools play an important part in achieving this with design optimization subject to the capabilities of AM technologies. Therefore, the bus frames department (RBRF) in Scania CV AB, Södertälje wanted to examine the synergies between topology optimization and Design for AM (DfAM) in the context of this thesis. In this thesis, a methodology is developed to establish a DfAM framework involving topology optimization and is accompanied by a manufacturability analysis stage. A case study implementation of this developed methodology is performed for validation and further development. The case study replaces an existing load bearing cross member with a new structure optimized with respect to weight and manufacturing process. It resulted in a nearly self supporting AM friendly design with improved stiffness along with a 9.5% weight reduction, thereby proving the benefit of incorporating topology optimization and AM design fundamentals during the early design phase.
Ökad användning av Additive Manufacturing (AM) i industriell produktion kräver ett nytänkade av produkter (enheter, delsystem) ur AM-synvinkel. Simuleringsdrivna designverktyg spelar en viktig roll för att nå detta med designoptimering med hänsyn taget till AM-teknikens möjligheter. Därför ville bussramavdelningen (RBRF) på Scania CV AB, Södertälje undersöka synergierna mellan topologioptimering och Design för AM (DfAM) i detta examensarbete. I examensarbetet utvecklas en metodik för att skapa en DfAM-ramverk som involverar topologioptimering och åtföljs av ett tillverkningsanalyssteg. En fallstudieimplementering av denna utvecklade metodik utförs för validering och fortsatt utveckling. Fallstudien ersätter en befintlig lastbärande tvärbalk med en ny struktur optimerad med avseende på vikt och tillverkningsprocess. Det resulterade i en nästan självbärande AM-vänlig design med förbättrad styvhet tillsammans med en viktminskning på 9,5 %, vilket visar fördelen med att integrera topologioptimering och grundläggande AM-design tidigt i designfasen.

Layered manufacturing (LM) technologies are a class of additive manufacturing processes which create three dimensional geometries directly from CAD data sequentially layer by layer. This group of technologies can process a variety of metallic, polymer and ceramic materials, as liquids, powders, or solid sheets or filaments. The material can be processed using a laser, such as melting a powder or curing a polymer resin or consolidated using a binder deposited from a print head. The build methodology used in all LM is fundamentally a start-stop process since the deposition of material and processing of each layer occurs ~equentially. Hence, the build rate can be slow (2 - 6 Layers per minute); consequently, LM technologies have largely found application as prototyping tools to speed up product development. In order for these technologies to be adopted as rapid manufacturing (RM) methods to directly manufacture complex components which cannot be manufactured by other means these speed limitations need to be addressed. This Thesis describes a new high speed RM process, Spiral Growth Manufacturing (SGM), whereby 3D parts are built by simultaneously depositing, levelling and selectively consolidating thin powder layers onto a rotating build platform. This build configuration has several advantages when compared to conventional layered manufacturing systems: firstly, the process is continuous with no layer preparation overheads; secondly, the material deposition and solidification process can be performed simultaneously by the addition of further 'build stations' radially distributed about the circumference of the machine. The work presented in this thesis focused on the design, development and testing ofthe Spiral Growth Manufacturing process. Two machines were developed; one used a bank of stationary inkjet heads to print material, either as a binder into a powder layer or as hard material from mixing two printed ink solutions and the other machine used a 90 W, flash lamp pumped Nd:YAG laser to process metal powders by localised melting. The main objective ofthe testing phase was to produce simple 3D objects from solidified layers by: a) ink jet printing a binding agent into the deposited plaster powder layers; and b) ink jet printing reactive materials to form plaster directly. The second machine was developed to exploit the considerable knowledge of Selective Laser Melting (SLM) at Liverpool, with the modification of a research SLM machine to SGM operation.

The aim of this work is to establish the influence of the many process variables on the microstructure and the nature of internal stress in IN718 samples produced directly from powder using direct laser fabrication, which enables production of solid samples directly from a CAD file. The process variables that have been studied include, specimen geometry, laser power, laser traverse speed, the detailed laser path and powder feed rate. It has been found that the detailed microstructure is strongly influenced by all of these variables with the propensity for the production of equiaxed or columnar grains being strongly influenced by laser power. The texture is correspondingly strongly influenced by changes in processing conditions. The extent of precipitation of the various phases expected in IN718 was also found to be influenced by the process conditions. The level and nature of the residual stress in the sample and in the substrate have been determined for a wide range of experimental conditions and using neutron diffraction. It has been found that the level of these stresses could be reduced to a minimum value of about 300 MPa, but could not be eliminated. A simple 3D thermo-mechanical model was developed to understand the residual stress distribution, which agreed closely with the experimental measurements.

Annotation:

This paper focuses on an emerging manufacturing technology called Additive Manufacturing (AM) and its potential to become a more efficient and cleaner manufacturing alternative. This work is built around selected case companies, where the benefit of AM compared to other more traditional technologies is studied through the comparison of resource consumption. The resource consumption is defined as raw materials and energy input. The scope of this work is the application of AM in the scale model kit industry. The method used is the life cycle inventory study, which is a subtype of life cycle assessment (LCA). The result of the paper is the quantification of raw materials and energy consumption. The outcomes shows that AM has higher efficiency in terms of materials usage, as a higher proportion of materials ending up in the final product. Injection Molding (IM), on the other hand, wastes a significant proportion of raw materials in components that are not part of the final product. If the same or similar raw materials are used in both manufacturing methods, the advantage is clearly with AM. However, AM has higher energy consumption in comparison to the injection molding technique (IM). In terms of energy consumption, AM only has an advantage in this area when working with a very low production volume. The analysis of the energy consumption shows that most of the energy used in AM is to create the final product, while IM only uses a fraction of the total energy to produce the final product. AM technologies are still very new but have the potential for development and reduction of energy consumption in the future. Added to this potential is the higher materials usage efficiency of AM, which reduce the waste of materials and the energy, embedded in them. These two factors are likely to position AM as cleaner manufacturing alternative.

Annotation:

Low emission combustion is one of the most important requirements for Industrial gas turbines. Siemens Industrial gas turbines SGT-800 and SGT-700 use DLE (Dry Low Emission) technology and are equipped with 3rd generation of DLE burners. These burners demonstrate high performance and reliable operation for the duration of their design lifetime. The design and shape of the burner tip is of great importance in order to achieve a good fuel/ air mixture and at the same time a resistance to the fatigue created by heat radiation input. This gives a requirement for a tip structure with delicate internal channels combined with thicker structure for load carrying and production reasons. It was found that the extension of the burner lifetime beyond the original design life could be accomplished by means of repair of the burner tip. Initially the tip repair has been done by conventional methods — i.e. cutting off the tip and replacing it with a premanufactured one. Due to the sophisticated internal structure of the burner the cuts have to be made fairly high upstream to avoid having the weld in the delicate channel area. Through the use of AM (Additive Manufacturing) technology it has been possible to simplify the repair and only replace the damaged part of the tip. Special processes have been developed for AM repair procedure, including: a) machining off of the damaged and oxidized tip, b) positioning the sintered model on the burner face, c) sintering a new tip in place, d) quality assurance and inspection methods, e) powder handling, f) material qualification including bonding zone, g) development of methods for mechanical integrity calculation, h) qualification of the whole repair process. This paper describes how we have developed and qualified SGT-800 and SGT-700 DLE burners repair with the help of additive manufacturing technology and our research work performed. In addition, this paper highlights the challenges we faced during design, materials qualification and repair work shop set-up.

Annotation:

An oft-cited benefit of additive manufacturing (AM), or “3D-printing,” technology is the ability to produce parts at the point of use by downloading a digital file and making the part at a local printer. This has the potential to greatly compress supply chains, lead times, inventories, and design iterations for custom parts. As a result of this, both manufacturing and logistics companies are investigating and investing in AM capacity for production at the point of use. However, it can be imagined that the feasibility and benefits are a function of size, materials, build time, manufacturing complexity, cost, and competing technologies. Because of this, there are instances where the viability of point-of-use manufacturing ranges from the perfect solution to the worst possible choice. Unsettled Topics on the Benefits of Additive Manufacturing for Production at the Point of Use in the Mobility Industry discusses the benefits, challenges, trade-offs, and other determining factors regarding this new level of AM possibilities.
